After installing this new 4.12.0.0 SL version on my RPi5 8GB and the latest bootloader, the runtime disappeared after 15secs. The bootloader my pi uses is from 2024-06-11. I was able to resolve this issue using this post: https://forge.codesys.com/forge/talk/Runtime/thread/be25c0ff66/ The workaround works for me.

Hi, Yes it seems the program will not fit in your PLC memory. To resole this you can use the parameters in the CoUnit library to limit the various array sizes.

Hi, there is a plethora of hardware available for it to be succesful on. In theory every ARM32/64 or x86/64 device is a potential target. Next to this there are embedded device platforms for which specific toolchains are available. A good starting for manufactureres of CODESYS capable devices is available here: https://www.codesys.com/the-system/codesys-inside.html. That should give you a good reference point.

You are reacting to a post from over a decade ago.

You define a Result in your PLC code, to monitor wether the SysProcess.SysProcessExecuteCommand returns a succes or fail.

Dear Tim, Thank you for sharing this code, great stuff and works well 👍 Few remarks: the title implies that OSCAT is referenced and needed. To my surprise, this is not the case as it uses the netbase libraries (which you are fully aware off ;-) ). So, I am guessing that you meant this library is "inspired" by the OSCAT solution(?) Apart from some minor stuff like implementing currently non-existing ENUMS for use in the CASE statement and a proper FTP_ERRORS ENUM, it works very well. KUDOOS! With...

Hi, A small primer on how to go started. You should not change the path of the xml file via Python unless you fancy a challenge. Try changing via the supposed manner: via the new lib parameter interaction window (SP19 or newer) or change it in the .library and save it (recommended for older then SP19). The lib is open source so you may do whatever you see fit. I suggest you open the lib and explore/read it as this will help you write code for step2, monitoring the successful dump of the XML file...

you are most likely affected by this security fix: Codesys Advisory 2023-01 get the files from Program data or change that setting (Forceiecfilepath) to zero. hope this gives you enough hints

1) If you keep the default directory, is the file written? => The anwser should be YES if the unittest doesn't hang (i.e all test finish regardless outcome). 2) If you change the Default directory, is the file written? => If No: - check your PATH notation in CODESYS(!), - check the file write FB error messages, - check if the unittest doesn't hang (i.e all test finish regardless outcome). The XML file is only dumped at the end of all the tests. If the xml file is incomplete, assign a bigger filebuffer...

Its quite simple: the main fault was most probably somewhere in your filepath syntax. Read up on the FileRead/FileWrite/FileOpen and FileClose FB's from CAA File Library for hints on the path's syntax: CAA.FILENAME which is described in “CAA_Types.library“ should be usable for library “CAA_File“ in the following way. Separators between directory paths in “CAA.FILENAME“ are the slash („/“) or the back-slash („\“). The interpretation of the directory path is tolerant to the effect that either one or...

I'd prefer programming individual signals over BYTE or WORD/ DWORD assigned boolean channels. Usually individual channel assignment makes your code read way easier both at the hardware IO mapping and in the FB or PRG itself. The slight cost of declaring more channels usually adds tremendous added value for well readable code. The adagio in modern days is readability over compact programming. PS read up on PLCOPen programming style guidelines, they forbid you from using of direct adressing.

VAR_IN_OUT is technically a pointer so yes it is absolutely the way to go
-
The concept is really quite simple as the followings steps will explain it 1) Define a Struct of your choice, 2) Define an FB of your choice, 3) Instanciate the struct from 1 into a VAR_IN_OUT of 2 4) Instanciate the FB somewhere in a program 5) In your hardware you can now refer to the VAR_IN_OUT from 4 i.e. Application.PLC_PRG.MyFBinstanceOfStep4.iSomeInputAsBool;

Creating instances from FB's is tecchically not even OOP as this part of procedural programming. Procedural programming is a 4th gen language like C or PASCAL orIEC 61131-3 2nd edition Structured Text OOP is introduced in 5th generation programming languages like C++, Delphi or IEC 61131-3 3rd edition Structured Text.

In my example I assume that you are known with how you can access IO. There are several ways possible to access IO fully symbolic. Please read up on thisi. the manuals fro CODESYS. 1) define symbols on each channel in the IO list. These symbols are now directly accessible in your code. This is what I used in my example. 2) A more elegant way is to pre-define an IO Struct DUT type. This DUT type should now be defined in a funtion block or Program as VAR_IN_OUT. After This you should declare this FB...

PumpMotor(); //Calling the main FB body which on the inside calls a private method Pump-Manager, which probably manages the internal handling of the pump OPump1Start := PumpMotor.Start; PumpMotor.FeedbackOn := IPump1Feedback; PumpMotor.Fault := IPump1Fault; instead of using properties, like above I'd choose to go with methods but that is a matter of taste I guess.

Hi, if you use OOP, please refrain from using IEC hardware adresses! Write code entirely symbolic. So, in general, avoid hardcoded hardware adressing at all time.

If you are able to restore your current license onto the dongle then you are set. However worst case you buy a new one and park on a dongle. 1st takeaway is always use either a dongle or the remote licensing possibility from Automation Server. Elephant in the room: 2nd takeaway is you using the pi license in the plant, as stated in the EULA of the Pi specific runtime. The runtime is cheap for a reason as the hardware itself is NOT meant for that environment. Tip: To avoid SD Card corruption use a...

An extra idea is to buy a dongle. Though it wont save your SD Card, it keeps your licenses safe and portable. This is a bonus you cannot use right now.

Hi, I run 18.30 and 18.40 in Win11 without such issues. My first guess would be that this is user rights/policies related. Did you install and start codesys with admin rights?

Hallo, Mein Deutsch ist verrostet aber ich probiere es einmal. Ich vermutte das deine setup schon functoniert. Installation des packages dauert immer ein lange weile. Probiere es mit dem normale Interactive setup (nicht via CLI). Denn muss es auch functionieren und kann mann nachdem das via CLI ausprobieren. Good luck! PS update CODESYS installer auch selbst nach neuestem version.

Hi, The best advice I can give you is to follow a introductory PLC programming course. This course will allow you to get familiar with the available programming languages, how to interpret them and similarities/distinctions between them. The course will hopefully also explain the handling of the generic (PLCOpen) Execute / Busy / Done / Error / ErrorID mechanism. Such a course may be found on Lynda or similar or you could invest in a good book like "The book of CODESYS" which also explains these...

Hi all, Yes this feature seems to take away a lot of manual labor and creates unified device agnostic webpages. Could you please shift this feature up from the backlog? I think lots of customers (incl. me) would like to use this tool.

Some remarks, for official suppport you should always reach out to the oem, the original equipment manufacturer, in other words the brand/make PLC supplier. When asking for help, you should always ask concise questions and explain every detail/step to reproduce the issue. Some questions I have are: what is the brand and type of PLC you are using? What is the type of connection you are using to programm the controller? Are you running the latest FW in your PLC? Etc andsoforth. I hope you can provide...

Hi, If you call / mail with Teltonika support, you would have found out that what you are doing is not supported and therefore probably will not work. Please check this with your reseller, mine told: NO not supported with Teltonika. Advice is to search for a WIFI extender that supports Profinet and explicitly states this in the specs. I know Phoenix Contact and Siemens sell these, try google. With regards,

a super easy way for a Watchdog signal is just to add a global var iWdTaskX and tally it up every cycle. If you have more tasks running just name them accordingly so in task XYZ we program a single line of code somewhere; GVL.iTaskXYZ := GVL.iTaskXYZ + 1; Remember that a change in value matters and as long as the current value differs from the last received value we are gold.

Another possibility would be to write a class around the array of strings which does the housekeeping for you. the main advantage is that your housekeeping code is neatly placed in a single spot.
